Azt a pletykát (mint minden pletykát
) erős fenntartással kezelném az SMT-t honnan vették? (a forrásul szolgáló kínai oldalt nekem nem volt képes lefordítani gugli angolra).A SkyBridge projektben fut össze az AMD IP stratégiája
AMD Core Innovation Day prezentációElső lépésben egyébként a jó fogyasztás/teljesítmény arányú Puma+ (Jaguar utód) processzorokhoz lesz szerencsénk, amelyek az ARM alapú testvéreikkel közös foglalatot kapnak, BGA-s variánsuk megjelenését követően (hasonló folyamat lehet majd, mint ami Kabini esetében zajlik A6-5200 FT3 BGA -> Athlon 5350 AM1 [FS1b] uPGA ill. vagy az idei éve Q3-ban esetékes Beema [BGA] megjelenés asztali vonalon).
Jim Keller visszatérésével kapcsolatban (aki AMD legjobb K7 és K8 architektúrái felett bábáskodott. Valamint kulcsszerepet játszott az Apple megfelelő chipválasztásában is).
The veteran processor architect got "a whole lot of new ideas working with both" ARM and x86 cores. But he gave only a few oblique hints on what AMD's ambidexterous chips might look like.
They will be closer in frequency to the 4 GHz of AMD's latest Kaveri x86 SoC than today's 2 GHz ARM chips, he said. For Skybridge, AMD tweaked its new Puma x86 cores to look more like an ARM V8 core.
AMD upgraded its current on-chip fabric, I/O and memory-management units so they could accommodate either the Puma+ or standard ARM cores in Skybridge. The fabric gets an upgrade for the custom ARM cores coming in 2016, probably made in a 16/14nm FinFET process.
"We got the IP, SoC and fabric right, then worked on how to plug the cores into them," he said. Skybridge provided an opportunity to "get the [SoC] plumbing right," he added.
Keller suggested AMD will consolidate its work on separate Bulldozer and Jaguar x86 cores into one processor line in the future. Meanwhile, the team had to bring up new verification and design flows for ARM SoCs.
Much of the architectural work on the upcoming AMD chips is done and the company is well along in implementing them, Keller suggested. AMD is apparently already well along in the custom designs that will use a 16/14nm FinFET process that he said "looks pretty good, we're happy with it."
"We are doing a new x86 and a new ARM core and a new [SoC] methodology -- that’s pretty daunting," Keller said.
"The fact Jim Keller came back [to AMD from Apple] telegraphed they would do something interesting -- he's the real deal," said Kevin Krewell, principal analyst of Tirias Research.
Idézet K12-ről AMD hivatalos oldaláról.
AMD's ambidextrous computing roadmap includes:
"Project SkyBridge" - This design framework, available starting in 2015, will feature a new family of 20 nanometer APUs and SoCs that are expected to be the world's first pin-compatible ARM and x86 processors. The 64-bit ARM variant of "Project SkyBridge" will be based on the ARM Cortex®-A57 core and is AMD's first Heterogeneous System Architecture ("HSA") platform for Android; the x86 variant will feature next-generation "Puma+" CPU cores. The "Project SkyBridge" family will feature full SoC integration, AMD Graphics Core Next technology, HSA, and AMD Secure Technology via a dedicated Platform Security Processor (PSP).
"K12" - A new high-performance, low-power ARM-based core that takes deep advantage of AMD's ARM architectural license, extensive 64-bit design expertise, and a core development team led by Chief CPU Architect Jim Keller. The first products based on "K12" are planned for introduction in 2016.
